One technology site notes "numerous reports from users who claim to have never synchronized their contacts with Facebook's mobile apps, yet still find all of their contact data stored on Facebook's servers." Even if your friends don't have Facebook accounts, Facebook may still have their names and phone numbers. There's a six-click path through each user's "Account settings" which ultimately leads to a page for re-claiming your friends' phone numbers, and "There is probably a clause buried deep within Facebook's terms and conditions that makes this invasion of your privacy OK on paper," this article notes. "But odds are still pretty good that it's not OK with you.""
